NAME:
Whiteness Meter
CATEGORY Other Lab Instruments

Introduction

  Whiteness meter is used for neutral flat material surface whiteness

measurement. Could be solid material or powder. Could exactly test

whiteness figure. Could directly test paper none transparent ratio.

It is widely used in fabric printing, paint and coating, chemical

and building material, paper, paper board, plastic products, white

cement, ceramic, talc powder, starch, flour, salt, detergent etc 

whiteness measuring. 

 

Character (WSB-3/3A;WSB-2A):

1. Microcomputer. Key touch board, LCD back light display. RS232 interface.

2. Quick several point auto calibration function, stable working, free maintenance.

3. Exactly testing result. Easy use, to measure paper opacity.

4. Use amendatory color filtration system. Its spectrum character

   complicate meet CIE standard observes responds curve. 

   Accurately get ISO whiteness figure.

5. High stability, completely eliminate system drifting effectiveness.

   Figure storage function, could meet GLP requirement. 

6. Use imported high quality parts inside. High working efficiency,

   little power consumption, good structure, could use long time.
